Abstract: The title compound, C15H15NO4S, was obtained by the condensation of 4-amino­aceto­phenone and 4-meth­oxy­benzene­sulfonyl chloride. The dihedral angle between the benzene rings is 86.56 (9)° and the mol­ecule has an approximate V-shaped conformation. The C atom of the meth­oxy group is roughly coplanar with its attached ring [deviation = 0.177 (3) Å], as is the methyl C atom of the acetyl group with its ring [deviation = 0.065 (2) Å]. An intra­molecular C-HO inter­action generates an S(6) ring. In the crystal, N-HO and C-HO hydrogen bonds link the mol­ecules into [010] chains. Weak C-H inter­actions are also observed.
